Title: Power supply changeover circuit
Inventor: SAJI MASAAKI
IPC: H03K17/62
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain the power supply changeover circuit by which a voltage which is highest among a plurality of power supply voltages is selected and outputted and destruction is prevented even for a bipolar transistor(TR) with a lower withstant voltage. SOLUTION: A 1st power supply system circuit 17 provides an output of a voltage (VBAT-VBE) based on a 1st voltage VBAT when the 1st voltage VBAT is less than a 1st setting voltage Vz. When the 1st voltage VBAT reaches the setting voltage Vz or over, the 1st power supply system circuit 17 provides an output of a voltage (Vz-VBE) based on the setting voltage Vz. A 2nd power supply system circuit 27 acts similarly like the 1st power supply system circuit 17. Thus, a voltage from the 1st power supply system circuit 17 or a voltage from the 2nd power supply system circuit 27 which is higher appears at a power supply voltage application node 3. Even when the 1st voltage VBAT and the 2nd voltage VUP exceed respectively the setting voltage Vz, the voltage appearing at the power supply voltage application node 3 is clamped to (Vz-VBE).

Filed: 1986-12-27
Abstract: PURPOSE:To prepare uniformly cooked rice, by estimating the quantity of rice when the temperature of the rice reaches a level lower than boiling point, continuing the supply of a prescribed high electrical power according to the estimated quantity of rice and continuing the cooking process under decreased electrical power supply. CONSTITUTION:In the cooking of rice by supplying electrical power to rice- cooking heater, a prescribed high electrical power is supplied to the heater and the quantity of the rice is estimated when the temperature of the rice reaches a level lower than the boiling point.

Title: Automatic feeding device for original
Inventor: MORI NORIYUKI
IPC: B65H1/06
Filed: 1988-12-15
Abstract: PURPOSE:To automatize the loosening of originals and improve a separating property by making the front end portions of originals an inclined face and guiding same to a separating portion by means of a guide while restraining the sending out of doubly bed originals by means of the guide at the time of sending out originals by a send-out means. CONSTITUTION:Originals G being sent out are brought into contact with the rubber member 28 of a revolving board 27, to revolve same centering around a supporting member 26 to a separating roller R2 side. Thereby, the originals G becomes an inclined shape along the rotary board 27 with the upper layer side being left behind due to the frictional force of the rubber member 28, to be handled so as to facilitate the separation of a first sheet. Then, the originals are separated and fed by means of a feed roller R3 and a separating roller R2. In this case, if double feeding occurs, the revolving end of the revolving board 27 permits the separating roll R2 to be brought into contact with the second and following originals G which are placed in a telescopical form with respect to the roller R2. Hence, the sending out of the second and following originals G can be prevented. By this structure, the automatic loosening of originals can be performed enabling sure separation.
